Hi,
I've been really reserved about telling people this time after the previous m/c. Only my partner, Mum and a good friend knew before I was 12 weeks - I would have found it too difficult to tell many people that I'd lost my baby.
7 months on from the m/c I can talk about it much easier, and have even recently told more friends and family that it happened but I've had to do it all in my own time. Oddly enough, one thing I didn't want when I miscarried was sympathy - when I think back I think I was pretty angry and blamed myself, maybe I didn't think I was worthy of it, not sure.
Anyway, I think it's really a very personal decision and you should do what you feel comfortable with. If your OH doesn't want to tell anyone perhaps you could come to a compromise where you just tell a few family and very close friends. All the best.
